For SSL protected connections the plug-in substitutes server SSL certificates for blocking spam by headers and for filtering IMAP.
To avoid TheBat/Voyager from displaying warnings it is possible to import the plug-in's root certificate to address book of email client:

i used TheBat 7.1.4 and today i buy this your antispam plugin.
But with POP3 all is ok but when i using full version with IMAP4 and have SSLConection so plugin not working.
All i have set + have this hint with certificate redy. But server still write me this error mesage:
FETCH - TLS handshake failure. Invalid server certificate. The certificate or one of the certificates in the certificate chain does not have a valid signature.
